What is the size of a sharpie marker cap?

The size of a Sharpie marker cap can vary depending on the type of Sharpie, but typically, the cap is about 1 to 1.5 inches long and around 0.5 inches in diameter. The cap is designed to fit snugly over the marker's tip to prevent it from drying out. If you're looking for exact dimensions, it's best to check the specific product details from the manufacturer's website.
